Animal Feeding and Nutrition PDF
by
Animal Feeding and Nutrition PDF, Animal feed is food given to domestic animals in the course of animal husbandry. “Fodder” refers particularly to food given to the animals (including plants cut and carried to them), rather than that which they forage for themselves. It includes hay, straw, silage, compressed and pelleted feeds, oils and mixed rations, and sprouted grains and legumes.
Animal feeding operations (AFOs) are agricultural enterprises where animals are kept and raised in confined situations. AFOs congregate animals, feed, manure and urine, dead animals, and production operations on a small land area. Feed is brought to the animals rather than the animals grazing or otherwise seeking feed in pastures, fields, or on rangeland.
Feed grains are the most important source of animal feed globally. The amount of grain used to produce the same unit of meat varies substantially. According to an estimate reported by the BBC in 2008, “Cows and sheep need 8kg of grain for every 1kg of meat they produce, pigs about 4kg. The most efficient poultry units need a mere 1.6kg of feed to produce 1kg of chicken.” Farmed fish can also be fed on grain, and use even less than poultry. The two most important feed grains are maize and soyabean, and the United States is by far the largest exporter of both, averaging about half of the global maize trade and 40% of the global soya trade in the years leading up the 2012 drought. Other feed grains include wheat, oats, barley, and rice, among many others.
Feeds, Feeding, and Animal Nutrition is the first text of its kind to finally pair ration formulation with the text to create a comprehensive learning solution. The animal feeding and nutrition industries are as computerized as any industry in the world, but the challenge has been to find software that can effectively accompany a text and give the student everything they need to succeed. This is a deficiency that has now been addressed.
